Ex: Students will analyse the lab data and investigations, then compare the results. Social Skills Practice giving feedback on the design of experimental methods. Ex: Students will work in groups and give each other feedback. Communications Skills Use appropriate scientific terminology, data tables and graphs to make the meaning of your findings clear to an audience of your peers. Ex: Students will represent their data in graphs and tables and communicate the results with other teams Self-management Skills Structure information appropriately in laboratory investigation reports. Ex students need to manage their time and work habits as a team to finish the lab, collect the data, clean the lab on time. Research Skills Make connections between scientific research and related moral, ethical, social, economic, political, cultural, or environmental factors. EX: Students will compare their data and conclusion with background research and reading to further their understanding

Date: 12/2 Goal: I can understand how height affects velocity in terms of energy TB p. 367 #1- 3

Potential Energy Potential energy (PE) = stored energy of position possessed by an object Examples: The ball of a demolition machine A stretched bow Coconuts in a tree There are 2 types of potential energy:

1. Gravitational Potential Energy Gravitational potential energy = (PEgrav) the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth for the object.  Example: The PEgrav of the massive ball of a demolition machine is dependent on two variables - the mass of the ball and the height to which it is raised.

Kinetic Energy Kinetic Energy = (KE) energy of motion There are many types of kinetic energy, but we are going to focus on only one type: energy due to motion from one location to another. Examples: Roller coasters going downhill Skateboarding up and down a half-pipe Wind

Calculating GPE GPE = mgh m = mass of object (kg) g = acceleration due to gravity on Earth it equals 9.8 m/s2 Δ h = change in height of object (meters) PEgrav units are Joules(J) because we are measuring energy. Recall the weight (w) is mass x gravity (w = mg). As a result, PEgrav can also be calculated if you are given weight. PEgrav = wΔh

Kinetic Energy Calculating KE KE = ½ m v2 ½ = 0.5 or half (constant with no units) m = mass of object (kg) v2 = velocity2 or velocity x velocity (m/s) KE units are Joules because we are measuring energy.

If engineers can use potential energy (height) of an object to calculate how fast it will travel when falling, can they do the reverse and calculate how high something will rise if they know its kinetic energy (velocity)? (Answer: Yes, as long as you know either height or velocity, you can calculate the other.)For what might an engineer use this information? (Answer: To create other amusement park rides besides roller coasters, in racing, or how to launch something, etc.)Why did the pendulum have the same period even when the weight started from different heights? (Answer: The period of a pendulum is only dependent on the length of the pendulum, which is consistent no matter where the weight starts.)
